Are 2-3 week touchups safe & effective?

Some laser hair removal places do touchups 2-3 weeks after your visit for free. They say it's good since it gets hairs that were missed or the laser wasn't effective on it the first time around. Others say touchups don't work, and others say you should give your skin 4 weeks to heal after a treatment. Are they safe? and do they worth it?

A 2 to 3 week touchup is neither safe nor effective.

Ever hear the expression, “There’s no such thing as a free lunch?” The sentiment applies here. Some laser hair removal centers may offer a free touchup at the 2 to 3 week marker, but this is not a safe practice. The reason why skilled, licensed laser technicians and cosmetic surgeons space each laser hair removal treatment approximately 4 to 6 weeks apart for the face and up to 8 to 12 weeks apart for the body is because that’s how long it takes for the new hair to be in the active phase, which is the only time that LHR can target and eliminate it. Laser hair removal done too soon is not only ineffective, it can also put the skin at risk for burning or scarring.

Laser Hair Removal and timing

Different areas of the body have hair that grows at different rates.  You need to have laser hair done at 4 or 6 or 8 week intervals depending on the body.  After you are all done with your treatments, you may require "touch ups" in the future if you grow new hair.  It is highly effective and please consult an expert.  Best, Dr. Green
